The rated magnetizing current determined during the guided commissioning procedure is set to an
optimized value and does not have to be adjusted.
718 Rated slip correction factor (asynchronous motor, field-orientated control)
The rotor time constant results from the inductivity of the rotor circuit and the rotor resistance. Due to
the temperature-dependence of the rotor resistance and the satura-tion effects of the iron, the rotor
time constant is also dependent on temperature and current. The load behavior and thus the rated
slip depend on the rotor time constant. The guided commissioning determines the machine data dur-
ing the parameter identification and sets the parameter
The value calculated by the rotor time constants can be read out via the actual value
227. Parameter identification (during guided commissioning "Setup") should be done

The auto-setup during the guided commissioning (setup) identifies the voltage constant of the syn-
chronous motor. If a value > 0 mV was entered before manually, the voltage constant will not be
determined during auto-setup. The entered value is maintained.
For the voltage constant, refer to the motor data sheet. In the motor data sheet, the value may be

The voltage constant should be optimized after the guided commissioning procedure: In no-load op-
eration, set 50% of the rated speed. Change the voltage constant in small steps until parameter

In the case of motors with a very high number of pole pairs (e.g. higher than 20), it is
possible that the maximum setting range of the parameter is not sufficient. In this
case, divide the voltage constant by 10 and enter the value. The division by 10 is con-
sidered internally.
